Mr. Hallworthy

Mr. Hallworthy is one of the Smith's neighbors. He heads off to the neighborhood party with a crock pot full of mousetraps to prove he's a crazy old man in "I Can't Stan You". Roger decides to scam him by tripping on his sidewalk and convinces Steve to go along. Later, Mr. Hallworthy is part of the entire neighborhood that is rounded up and sent to the Cornfield Motel when Stan finds out the neighbors think he his a jerk.

Steve later finds Mr. Hallworthy's body in "Red October Sky" where Hayley speculates he'd been dead for weeks. Former Soviet spy Sergei Kruglov moves into his house.
